Hypoplastic superficial femoral artery combined with connection of the deep femoral artery to the popliteal artery

The most common anatomical variation of the superficial femoral artery (SFA) is hypoplasia or aplasia associated with a persistent sciatic artery. We report a case exhibiting SFA hypoplasia combined with connection of the deep femoral artery (DFA) to the popliteal artery (in other words, the DFA became the popliteal artery). A 41-year-old man was admitted with a crush injury of the left foot. Computed tomography angiography revealed an SFA branched off the anteromedial side of the common femoral artery and exhibited severe hypoplasia and the DFA branched off the posterolateral side of the CFA and continued to become the popliteal artery.
